This may be of interest to people who can get old Dell PowerEdge Server supplies for free/cheap:
http://www.gekkoscience.com/products/D750_supply_breakout_board.html
At $42.50 per board (+ power supply itself) it's not exactly cheap, however it's going to be quite efficient and clean high current 12V power. The weird Dell PSU connector itself is actually about $10 alone too.
Other features:
[SIZE=medium]+ 5V and 3.3V outputs for driving auxiliary controllers.[/SIZE]
[SIZE=medium]+ The current share pin to tie together if you wish to use more than one power supply at a time.[/SIZE]
[SIZE=medium]+ Current sense pin, to measure current consumption.[/SIZE]
[SIZE=medium]+ External fan speed controller.[/SIZE]
[SIZE=medium]+ External on for turning more than one supply on at the flip of a single switch.
+ Power good signal to indicate whether the supply is functioning properly.[/SIZE]
...And yes, these can be joined in parallel together to increase output power. The other cheap option is no fancy management and just solder directly to the PSU's voltage pins.
